To ALLWHOM rr MAY co'NcERN:

Be it known that I, JOSEPH STEGER, of No. 24 Suifolk street, New York, in' the county and State of Newv York, have invented a new and useful YImproved Hosc-Couplingg 'and I do hereby declare that the following is a full,fclear, and exact description thereof, \vhich will enable those skilled in the art to make and use the same, reference'bcing had to the accompanying drawing, forming part of this specification` in which drawing- Figure 1 represents a longitudinal central section of the female half-coupling. Figure 2 is a side elevation of theV malle half-coupling.

Figure 3 is a transverse section of the coupling when put together, the line :i: x, fig; 1, indicating the plane of section.

Similar letters of reference indicate corresponding parts. Thisinvention relates to a. hose-coupling in which each of the half-couplings is provided with two or more 'teeth withl inclined faces, in combination with a set-screw, which is tapped into the side of the female halfcoupling in such a mannerthat by inserting the male half-coupling into the female half-coupling, a. slight turn given to the half-couplings, or one of them, in the proper direction, will cause the teeth to interlock, and, by screwing up the setscrew,"theinclined faces of said teeth are made to slide over-each other, and the end ofthe male half-coupling is pressed up tight against a suitable packing introduced into the female half-coupling, and n coupling is obtained which can be coupled and vuncoupl-edwith ense and rapidity, and which, when coupled, forms a tight-joint,

v A represents the female half of my coupling, :1nd B the male-half, said half-couplings being cast or otherwise produced of brass, iron, or any other suitable material. Each o f the half-couplings is provided with twp or more teeth a a, b b, the faces of which form inclined planes, and which nreso situated that theteelh I of th male halfcoupling can be made to pass in between the teeth a of the female half-coupling, and that, by slightly turning the male half-coupling in the direction of the arrow marked on it in fig. 3, the inclined faces of 'the .teeth 6 interlock 'with those ofthe teeth a. Through' the side ofthe female half-coupling A passes a set-screw, e, in such a position that when the two half-couplings nre put together, the point ofsaid screw can bemolle to bear-on the back of one of the teeth b, and by screwing np said screw, the inclined faces of the teeth b are caused to slide overthe inclined faces ofthe teeth u,nnd thereby the end of the male hulf-coupling Bis pressed up firmly against a packing-ring, d, inserted into the female half-coupling A, as shown in fig. .1 of the'drawing. By these means a tightjoint'is produced between the half-coupling, and furthermore the two lhalf-couplings are firmly united, and they have no chance to disconnect themselves until the screw c is turned back far enough to allow of disengaging the teeth b from the teeth a, which will be effected by turning the half-coupling B in the direction opposite the arrow marked on it in iig. 3. l

A coupling made according to Vthis invention is very cheap, it is durable, and not liable to get ont of repair, and itvcan be coupled and uncoupled very expeditiously, and without being obliged to turn eilher'of the half-couplings 4round and round. The teeth. a b of my two half-couplings will interlock quite readily, and by screwing up the set-screw c, the two half-couplings nre firmly united, and a tightjoint is formed between them. It remains to remark tl1at'the screw could be replaced by an eccentric-lever, or otherdevice of a similar nature, which I would considerequivalents of the set-screw. 1 y What I claim as new, and desire to secure by Letters Patent, is

The tcetha a, b and set-screw c, or it's equivalent, in combination with the two half-couplings A B, constructed and operating substantially as and for thepurpose set forth.

JOSEPH STEGER.
